Pops up logging messages as message boxes.

Namespace:  NLog.Targets
Assembly:  NLog (in NLog.dll) Version: 2.0.0.0

Syntax

C#
public sealed class MessageBoxTarget : TargetWithLayout
Visual Basic (Declaration)
Public NotInheritable Class MessageBoxTarget _
	Inherits TargetWithLayout
Visual C++
public ref class MessageBoxTarget sealed : public TargetWithLayout

Examples

To set up the target in the configuration file, use the following syntax:

CopyXML
 1<?xml version="1.0" ?>
 2<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
 3      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 4    <targets>
 5        <target name="msgbox" xsi:type="MessageBox" layout="${longdate}: ${message}" caption="${level}" />
 6    </targets>
 7
 8    <rules>
 9        <logger name="*" minlevel="Debug" writeTo="msgbox" />
10    </rules>
11</nlog>

This assumes just one target and a single rule. More configuration options are described here.

The result is a message box:

To set up the log target programmatically use code like this:

CopyC#
 1using System;
 2
 3using NLog;
 4using NLog.Targets;

 7{
 8    static void Main(string[] args)
 9    {
10        MessageBoxTarget target = new MessageBoxTarget();
11        target.Layout = "${longdate}: ${message}";
12        target.Caption = "${level} message";

14        NLog.Config.SimpleConfigurator.ConfigureForTargetLogging(target, LogLevel.Debug);
15
16        Logger logger = LogManager.GetLogger("Example");
17        logger.Debug("log message");
18    }
19}
